Description

一种轧机用推力调心滚子轴承
技术领域
本发明涉及一种轧机用推力调心滚子轴承，属于推力轴承技术领域。
背景技术
推力调心滚子轴承由于具有结构紧凑、密封完善、装卸方便和自动调心幅度较大等优点，它的特点是：用于承受轴向载荷为主的轴向和径向联合载荷，但径向载荷不得超过轴向载荷55％。与其他推力轴承相比，此种轴承摩擦因数较低，转速较高，并具有调心性能。本发明所列的推力调心轴承为经过优化设计的加强型轴承。此种轴承的滚子为非对称型球面滚子，能减小滚子和滚道在工作中相对滑动，并且滚子长、直径大，滚子数量多，载荷容量高，通常采用油润滑，个别低速情况可用润滑脂。
推力滚子轴承采用钢或者铜制造实体保持架；由于座圈滚道为凹球型，允许轴与外壳轴线有一定的倾斜角。推力滚子轴承在运转中滚动体受离心力拒作用，滚动体和滚道之间相对滑动，导致轴圈和座圈分离，为保证轴承正常工作，必须施加一定的轴向载荷。
发明内容
本发明为解决以上的技术问题上，提供了一种轧机用推力调心滚子轴承，解决了装配困难等问题。
本发明的一种轧机用推力调心滚子轴承包括外圈、内圈、滚子、保持架和内圈衬；所述内圈衬套在内圈中；所述滚子均套在保持架中。所述内圈衬呈阶梯圆环形；内圈衬上部是细薄圆环形；内圈衬下部是粗圆环形，粗圆环形上侧倒角。内圈呈倒圆锥环形，外侧有一滚子滚道；外侧顶部的外边倒圆角；内圈外侧顶部有一突出的圆环，圆环上有一方向沿轴向向下的圆锥凸环；圆锥凸环和圆锥面之间有一圆弧凹槽；内圈内侧有阶梯孔，上阶梯面和下阶梯面之间有圆锥槽，阶梯孔的两侧倒圆角、上侧的圆角大于底侧的圆角。保持架呈圆锥环形，保持架的上侧有梯形齿牙，齿牙之间的空间可以容纳滚子。
推力滚子轴承的内圈衬装在内圈上后，通过冲压使内圈衬固定在内圈上，从而保证了内圈衬和内圈的紧固连接，使轴承能够稳定的工作。
本发明的推力调心滚子轴承具有结构紧凑、密封完善、装卸方便和自动调心幅度较大等优点，从而改善了工作条件、大大提高了轴承寿命。
附图说明
图1是本发明轴承的剖面结构图；
图2是本发明安装在内圈上内圈衬的剖面结构图；
图3是本发明未安装在内圈之前内圈衬的剖面结构图；
具体实施方式
本发明由图1可知：轧机用推力调心滚子轴承包括外圈、内圈、滚子、保持架和内衬圈；所述内圈衬套在内圈中；所述滚子均套在保持架中。所述内圈衬呈阶梯圆环形；内圈衬上部是细薄圆环形；内圈衬下部是粗圆环形，粗圆环形上侧倒角。
一种优选实施方式：以公称外径为360mm的推力调心滚子轴承为例：外圈的公称宽度为85mm，公称内径为220mm；内圈衬的大圆环直径为246mm，小圆环直径为226mm，内圈衬的高度为29.5mm。
